What happens to the shape of an enzyme at high temperatures?

Back

The shape of the enzyme changes, which can decrease the rate of biochemical reactions.

Front

What type of molecule do whales primarily use for energy storage?

Back

Whales use fats for energy storage and insulation.

Front

What determines the order of amino acids in a protein?

Back

The order of amino acids in a protein is determined by the DNA located in the nucleus of the cell.

Front

What are proteins made of?

Back

Proteins are made of amino acids.

Front

To which group of organic molecules do waxes belong?

Back

Waxes belong to the group of organic molecules known as lipids.

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes act as catalysts to speed up biochemical reactions by lowering the activation energy.

Front

What is the primary function of lipids in living organisms?

Back

The primary functions of lipids include energy storage, insulation, and forming cell membranes.

Front

What are the building blocks of nucleic acids?

Back

The building blocks of nucleic acids are nucleotides.

Front

How do temperature changes affect enzyme activity?

Back

Temperature changes can affect enzyme activity by altering the enzyme's shape, which can lead to decreased reaction rates.

Front

What is the difference between saturated and unsaturated fats?

Back

Saturated fats have no double bonds between carbon atoms, while unsaturated fats have one or more double bonds.
